| Research Abstract |
We have shown that in natural grand unified theory, the Kobayashi-Maskawa matrix can be derived by the spontaneous CP vilation, and pointed out the various phenomena predicted by the peculiar sfermion masses. Moreover, we have shown that in the light Higgs scenario, the thermal abundance of the neutralino tends to be smaller than the usual scenario. And we have found the two vacua in which E6 unified model with 3 families and adjoint Higgs is realized.
